Abstract

A check valve wherein a tubular housing confines a reciprocable valving element which is biased by a spring so that it normally engages a seat between the inlet and the outlet of the housing. The valving element is guided by a plastic core which is installed in the housing and has axially parallel guide members for the head of the valving element. One end of each guide member is integral with an annular stabilizing section which is received in a complementary internal socket of the housing, and the other end of each guide member is integral with an annular main section which is coupled to the housing by male and female detent members. The main section surrounds a sleeve-like bearing which guides a shank of the valving element.
